The table slides up and down to accomodate the material you are drilling.

Open the drill battery pack with a screwdriver and locate the chain of Ni-Cad batteries to be repaired. Pull these cells out of the Makita battery casing.

Determine how the cells are placed in line. Using a pencil and paper, jot down the polarity of the line of batteries. Note the pattern and how the cells fit into the casing for easier reassembly.

Test each individual Makita Ni-mh battery cell in the battery tester to determine which ones are bad. Mark the bad cells that will need replaced.

Purchase the same sized Ni-Cad replacement batteries. Only replace Ni-Cad batteries with Ni-Cad batteries. The type of batteries must remain the same throughout the battery chain.

De-solder the first "bad" drill Ni-Cad battery cell from the chain. Re-solder in the new Ni-Cad battery.

Repeat this process with the entire tool Ni-Cad battery chain until completely restored. Replace the chain within the tool battery case.

Place the cordless tool on the charger overnight and it should be as good as new.

It is the process of drilling a locating hole at the end of a shaft while machining between centres.

tell me what tools has 15% more power than another tool of the same line general power tools , what tools has 15% more power than another tools of the same line compare such as drills, circular saws.

Depends on the tool. Sears contracts different companies to build different tools. You can usually find the manufacturing company in the owners manual.

A tool that uses explosive cartridges as its source of force. For example a "nail" driver for use on concrete, it drives a 4 inch to 6 inch barbed "nail" instantly into concrete and sounds and smells just like a gun firing, even leaves powder burns on nearby surfaces.

A 'chuck key ' is used, there are 2-3 sizes.

At Sears.

You can study several courses after finishing diploma in electronics and communication engineering you can go for-

B.Tech from E&C

B.E

AMIE

and you can also go for other professional courses. like industrial automation

and training.

Because they will buckle if they are used dry.

The instruction tag on my 315.22600 says "2 drops of SAE 20oil in oiler at right side of front pulley"

Is it maybe a Scott technologies Signgraver motor?

Hand tools as suggested by the name are hand powered. Power tools all have a motor, usually electric.

Yes, they can, but don't achieve their full potential because of the much lower speeds

a good way to remove a metal bolt is to get a screw extractor. You drill a small pilot hole down the middle of the bolt, and lightly tap the extractor into the hole. The bolt will then twist out. You may need to add lube to the bolt if its rusted (WD-40 etc.)

First, make sure it is unplugged.

There should be a small black button at the the back of the saw blade housing, usually on the left hand side as you are facing the saw. It presses into the bracket that holds the hinge assembly.

Relieve some of the lateral pressure on the button by leaning lightly on the top of the saw blade housing and push the button in. It will reflex back out to your finger, so let it.

Be careful that the spring-tension in the hinge assembly does not cause the saw blade housing to smack you in the face, because it just might.

Happy cutting!

lubricated during cutting.

a perfect right angle hole every time, you can also use various forms to make repetitive holes, such as signs or for toys.

118 degrees from the axis of the bit is the most common drill bit angle. -There are sharper and more obtuse angles in specialised drill bits.

What type of jig are you using? Answer: Several thing must take place to use a Forstner bit, substrate must be held firmly, a drill press or fixture must be used to guide the bit in, here is an excerpt and the site: Drill bits are used in conjunction with hand drills or drill presses to make holes in woods, plastic and metals. A forstner bit is a particular type of drill bit that is often used in furniture making and other woodworking projects. They are usually more expensive than standard twist bits, but they have a few unique features that make them desirable. Most drills are guided through the material by a central point, but forstner bits are primarily guided by the outside rim. This means that they can be used to drill pocket holes (holes drilled at an angle), partially overlapping holes or holes that are on the edge of the material. Note that the central spur in the bit pictured below is used to locate by demarcating the center-point as opposed to being the drill guide. In addition to the previously mentioned benefits, forstner bits create square-bottomed holes which may be required for certain applications or projects. They are very efficient at removing large amounts (hogging) of material in short periods of time. Forstner bits are available in a wide array of diameters typically ranging from 1/4 inch up to over 3 inches (6 - 75mm). Like other drill bits, they are often sold in sets with an array of sizes. * http://www.wisegeek.com/what-is-a-forstner-bit.htm

Rivet guns are generally pretty simple. Usually 2 handles fit with a spring between on the jaw side. Show almost any tool person and they will know.

They can. Low end inverters often use a square wave output, instead of a sine wave output. This causes harmonic distortion that can sometimes damage equipment. One of the damage mechanisms is the simple rectifier - when the diode conducts and recharges the filter capacitor in a power supply, if the slope of the step change is vertical, as it would be with a square wave, the instantaneous current through the diode and capacitor tries to be infinite, and that can damage the diode or capacitor.
